TL;DR: The results not only prove Ta2NiS5 is a promising in-plane anisotropic 2D material but also provide an interesting platform for future functionalized electronic devices.
Journal ArticleDOI
New approaches for calculating absolute surface energies of wurtzite (0001)/(000 1¯): A study of ZnO and GaN
TL;DR: In this article, the authors used a pseudo-hydrogen passivation method to estimate the dangling bond energy and calculate the polar surfaces of ZnO and GaN, based on pseudo chemical potentials obtained from a set of tetrahedral clusters or simple pseudo-molecules, using density functional theory approaches.
Journal ArticleDOI
Pseudo-Hydrogen Passivation: A Novel Way to Calculate Absolute Surface Energy of Zinc Blende (111)/(͞1 ͞1 ͞1) Surface.
TL;DR: In this paper, a pseudo-hydrogen passivation method was proposed to calculate the surface energy of polar surfaces of semiconductors, using density functional theory approaches, and the energy contribution from pseudo hydrogen was calculated using either a pseudo molecule method or a tetrahedral cluster method.
Journal ArticleDOI
Surface energy calculations from Zinc blende (111)/(-1-1-1) to Wurtzite (0001)/(000-1):a study of ZnO and GaN
TL;DR: In this article, the authors used a pseudo-hydrogen passivation method to estimate the dangling bond energy and calculate the polar surfaces of ZnO and GaN, based on the pseudo chemical potentials obtained from a set of tetrahedral clusters or simple pseudo-molecules.
